18) Favorite antagonist and why!
I have a perverse desire to give the same answer to this one as I did the favorite protagonist question, since Akane Moroboshi/Radian of Superguy sometimes played the antagonist. And there’s no question she’s in the running, as she was fun to write in that capacity as well. But I think my answer to this one has to be the Creyts brothers, Gordon and Kelly, from Brutal Light.
They’re both dangerous, and mad in counterbalancing ways. Without one another, they would go off into the aether with their own peculiarities, and might be more fun to write in some senses, but less appealing as characters otherwise. Together, they have a sinister dynamic that was endless fun to write.
